Astronomy’s Vanishing Explorers

Astronomers wax romantic talking about the joys of traveling to remote places to observe the heavens. With today's technology, those kinds of trips are less and less necessary. What is gained and what is lost? We hear stories of death threats when an old-fashioned telescope malfunctioned and high-stakes technical difficulties caused by swarms of lady bugs and, more dangerously, erupting volcanoes.
